If there are subtitles i tend to focus on those instead of whatever else is happening on the screen
Been using subtitles all of the time since my wife is ESL and most films are English
It used to be rarely but now its pretty much always, even for shows shes not watching. Just got used to it and helps me pay attention to the dialogue more.
I'm also so averse to spoilers that it aggravates me when I can read ahead and see what a character will say before they say it. Ruins delivery and punchlines a lot.
